Abstract
Adjustable slot scraping tool.Because scientific research boiler and pressure vessels for the chemical industry product expansion-joint structure more and more generally used in recent years, and require also more and more stricter, need because of various reasons sometimes often to reprocess slot scraping device, delay the production cycle.The present invention, its composition comprises: taper shank (1), described taper shank connects the knife bar (3) with spring (2), grooving cutter (4) is equipped with in described knife bar one end, sleeve (5) is had at described taper shank and described knife bar overcoat, described sleeve one end connects adjusting nut (6), described jacket casing connecting bushing guard ring (7), described lining back-up ring connects locating snap ring (8) and bearing (9), described taper shank connects locking nut (10), and the described sleeve other end connects copper sheathing (11) and back-up ring (12).The present invention is used for groove scraping tool.
Description
technical field:
The present invention relates to a kind of novel groove scraping tool; Be specifically related to a kind of adjustable slot scraping tool.
background technology:
Because scientific research boiler and pressure vessels for the chemical industry product expansion-joint structure more and more generally used in recent years, and require also more and more stricter, need because of various reasons sometimes often to reprocess slot scraping device, delay the production cycle.And it is more expensive to purchase import instrument price, often cover just needs 2 ~ 30,000 yuans.Therefore, can design and manufacture the adjustable slot scraping tool with same function is active demand of the same trade always.
summary of the invention:
The cannelure that the object of the invention is to process a kind of specification aperture is example, can meet header or drum because of wall thickness has tolerance needs to finely tune, the key problem in technology that wall thickness difference carries out large scale adjustment can be met again, the phenomenon of stopping repeatedly to reprocess groove scraping tool occurs, improve the efficiency of workman, ensure the production cycle of product.
Above-mentioned object is realized by following technical scheme:
A kind of adjustable slot scraping tool, its composition comprises: taper shank, it is characterized in that: described taper shank connects the knife bar with spring, grooving cutter is equipped with in described knife bar one end, sleeve is had at described taper shank and described knife bar overcoat, described sleeve one end connects adjusting nut, described jacket casing connecting bushing guard ring, described lining guard ring connects locating snap ring and bearing, described taper shank connects locking nut, the described sleeve other end connects copper sheathing and back-up ring, at described taper shank and described knife bar junction, feather key is housed, between described knife bar and described sleeve, key is housed, described spring is contained in the knife bar other end, the large screw of described grooving cutter is fixed, described lining guard ring is screwed, described bearing has bearing block, described back-up ring is contained in one end of grooving cutter, described sleeve and described lining guard ring are threaded connection, and described taper shank is connected by fine thread with adjusting nut,
The external diameter of described copper sheathing is greater than the external diameter described sleeve being installed copper sheathing position sleeve, described feather key runs through described knife bar, described lining guard ring has a strip gap, the inner termination of described gap is circular arc, and the lining guard ring described in the both sides of described gap has the screw hole connected with screw;
Adjustment portion divides two parts: one is the adjustment of rear end adjusting nut, uses fine thread connected mode, tolerance can be had to need to finely tune because of supplied materials thickness, can need to carry out large scale adjustment because of different pipe thickness again; Two is adjustments of front end screw, and sleeve has scale, for regulating the degree of depth of processing cannelure;
Lock portion divides two parts: one is the locking of front end tightening nut, after working depth regulates, with the oval styletable holding screw locking of square toes; Two is the locking of rear end, the depth adjustment of processing cannelure well after, with locking nut and adjusting nut locking.
beneficial effect:
1. cost of the present invention is low, and manufacturing process simply can meet using function, and easy and simple to handle.
The grooving tool of often kind of specification of the present invention can process the grooving 25 ~ 65mm of different depth, and maximum cutting groove depth 1.5mm, the scope of application is large.
The present invention has regulation depth function compared with original design, and import Japan groove scraping tool expense is 2 ~ 30,000 yuans, this product adjustable type groove scraping tool cost only about 5000 yuan.
The present invention manufactures simply, with low cost, easy to use, and the copper sheathing material of this product is H62, avoids scuffing tube wall.
The present invention adopts three parts regulate and tighten, and namely screw, adjusting nut and tightening nut carry out regulating and tightening, make adjustment more accurately, tighten more reliable, operate convenient and reliable.
accompanying drawing illustrates:
The sectional view of accompanying drawing 1 product.
The front view of accompanying drawing 2 products.
Accompanying drawing 3 is A-A direction view of accompanying drawing 1.
detailed description of the invention:
Embodiment 1:
A kind of adjustable slot scraping tool, its composition comprises: taper shank 1, described taper shank 1 connects the knife bar 3 with spring 2, grooving cutter 4 is equipped with in described knife bar 3 one end, has sleeve 5 at described taper shank 1 and described knife bar 3 overcoat, and described sleeve 5 one end connects adjusting nut 6, described sleeve 5 overlaps connecting bushing guard ring 7, described lining back-up ring 7 connects locating snap ring 8 and bearing 9, and described taper shank 1 connects locking nut 10, and described sleeve 5 other end connects copper sheathing 11 and back-up ring 12.
Described adjustable slot scraping tool, at described taper shank 1 and described knife bar 3 junction, feather key 13 is housed, key 14 is housed between described knife bar and described sleeve, fix with screw 15 between described knife bar and described sleeve, described spring is contained in the knife bar other end, and the large screw 16 of described grooving cutter is fixed, and described lining guard ring is screwed, described copper sheathing material is H62, and described knife bar and described taper shank have 2mm or 3mm deviation.
Described adjustable slot scraping tool, described bearing 9 has bearing block 17, and described back-up ring is contained in one end of grooving cutter.The relevant part needing to regulate such as bearing retaining ring, adjusting nut to be regulated according to product requirement before this product uses, could use.
Embodiment 2:
Adjustable slot scraping tool described in embodiment 1, when the aperture of product is greater than φ 30.2mm, the knife bar front end of this groove scraping tool puts in one section of installation copper sheathing of holes of products, play guide effect, copper sheathing material is H62, avoids the manufactured inwall of scratch, and tolerance is strict, processing must put in place.
